Sedum plant named ‘Plum Dazzled’

ABSTRACT

A new cultivar of  Sedum  plant named ‘Plum Dazzled’ that is characterized by its very compact plant habit with stems that do not flop, it reaches about 23 cm (9 inches) in height and 46 cm (18 inches) in spread, its foliage that emerges medium gray-blue in spring and turns to very dark purple-black in mid summer, its flowers that are raspberry pink in color, and its high resistance to  Sedum  foliage blight and powdery mildew.

Botanical classification: Sedum hybrid.

Variety denomination: ‘Plum Dazzled’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sedum plant, botanically of hybrid origin and known as Sedum ‘Plum Dazzled’ referred to hereinafter by its cultivar name, ‘Plum Dazzled’. The new cultivar of Sedum is a hardy herbaceous perennial grown for use as a landscape and container plant and is particularly suitable as a groundcover.

‘Plum Dazzled’ arose from an ongoing breeding program conducted by the Inventor in Hudsonville, Mich. The goal of the breeding program is to produce new groundcover type cultivars of Sedum with compact, mounding, plant habits without the tendency to flop combined with dark purple foliage and abundant, large, and brightly colored raspberry pink flower heads.

The inventor made a cross in September 2008 between an unnamed, unpatented plant from the Inventor's breeding program as the female parent and ‘Zenox’ (U.S. Plant Pat. No. 16,888) as the male parent. ‘Plum Dazzled’ was selected as a single unique plant in September 2012 amongst the seedlings that resulted from the above cross.

Asexual propagation of the new cultivar was first accomplished by stem tip cuttings in May of 2009 in Hudsonville, Mich. Propagation by tip stem cuttings has determined the characteristics to be stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar. These attributes in combination distinguish ‘Plum Dazzled’ as a unique cultivar of Sedum.

-   1. ‘Plum Dazzled’ exhibits a very compact plant habit with stems     that do not flop. -   2. ‘Plum Dazzled’ reaches about 23 cm (9 inches) in height and 46 cm     (18 inches) in spread. -   3. ‘Plum Dazzled’ exhibits foliage that emerges medium gray-blue in     spring and turns to very dark purple-black in mid summer. -   4. ‘Plum Dazzled’ exhibits flowers that are raspberry pink in color. -   5. ‘Plum Dazzled’ has been observed to be highly resistant to Sedum     foliage blight and powdery mildew.

The female parent of ‘Plum Dazzled’ differs from ‘Plum Dazzled’ in having a smaller plant size (reaches 10 cm in height), inflorescences that are much smaller in size, smaller leaves, and gray-green foliage that does not change to dark purple-black in summer. The male parent, ‘Zenox’, differs from ‘Plum Dazzled’ in being larger in size (70% larger) and less compact, in having flowers that are light pink in color, and in having larger leaves (70% larger). ‘Plum Dazzled’ can also be most closely compared to the cultivars ‘Sunset Cloud’ (not patented) and ‘Dazzleberry’ (U.S. Plant Pat. No. 22,457). ‘Sunset Cloud’ and ‘Dazzleberry’ are similar to ‘Plum Dazzled’ in being a groundcover-type Sedum and in having medium dark gray foliage that turns purple in color. ‘Sunset Cloud’ differs from ‘Plum Dazzled’ in having purple foliage that is about 35% lighter in color with leaves that are smaller, less thick and dense, a taller plant height (30 cm) and a floppy plant habit. ‘Dazzleberry’ differs from ‘Plum Dazzled’ in having purple foliage that is about 35% lighter in color, an earlier blooming season (blooming 2 to 3 weeks earlier) and leaves that are slightly larger in size.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Sedum. The photographs were taken of plants about 9 months in age as grown outdoors in 1-gallon containers in Hudsonville, Mich.

The photograph in FIG. 1 provides a side view comparison of ‘Dazzleberry’ (left) and ‘Plum Dazzled’ (right) and depicted the more intense dark purple-black foliage of ‘Plum Dazzled’.

The photograph in FIG. 2 provides a close up view of the inflorescences of ‘Plum Dazzled’.

The photograph in FIG. 3 provides a close up view of the foliage of ‘Plum Dazzled’.

The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Sedum.
